Product Description

GN817.8 Indexing Plunger, Steel, Removable, with or without Rest Position

These versatile indexing plungers have been designed so that special versions of the indexing pins can be made economically in smaller unit quantities.

If required, the indexing pins can be machined by the user as shown in the drawing above. They are assembled with a countersunk screw and can therefore be taken apart and re-assembled if necessary. All parts are supplied in a non-assembled set.

The indexing plungers type C/CK are used for such applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° after being retracted. A notch keeps the plunger in this position.


Threaded body - Steel ST.

Plunger, Lock nut - Stainless Steel NI AISI 303.

Knob - Plastic (Polyamide PA), black, matt.

Also available in stainless steel
